Bytes utility

NPM Version NPM Downloads Build Status Test Coverage

Utility to parse a string bytes (ex: 1TB) to bytes (1099511627776) and vice-versa.

Installation

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

$ npm install bytes

Usage

var bytes = require('bytes');

bytes(number｜string value, [options]): number｜string｜null

Default export function. Delegates to either bytes.format or bytes.parse based on the type of value.

Arguments

| Name | Type | Description | |---------|----------|--------------------| | value | number｜string | Number value to format or string value to parse | | options | Object | Conversion options for format |

Returns

| Name | Type | Description | |---------|------------------|-------------------------------------------------| | results | string｜number｜null | Return null upon error. Numeric value in bytes, or string value otherwise. |

Example

bytes(1024);
// output: '1KB'

bytes('1KB');
// output: 1024

bytes.format(number value, [options]): string｜null

Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is rounded.

Arguments

| Name | Type | Description | |---------|----------|--------------------| | value | number | Value in bytes | | options | Object | Conversion options |

Options

| Property | Type | Description | |-------------------|--------|-----------------------------------------------------------------------------------------| | decimalPlaces | number｜null | Maximum number of decimal places to include in output. Default value to 2. | | fixedDecimals | boolean｜null | Whether to always display the maximum number of decimal places. Default value to false | | thousandsSeparator | string｜null | Example of values: ' ', ',' and '.'... Default value to ''. | | unit | string｜null | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to '' (which means auto detect). | | unitSeparator | string｜null | Separator to use between number and unit. Default value to ''. |

Returns

| Name | Type | Description | |---------|------------------|-------------------------------------------------| | results | string｜null | Return null upon error. String value otherwise. |

Example

bytes.format(1024);
// output: '1KB'

bytes.format(1000);
// output: '1000B'

bytes.format(1000, {thousandsSeparator: ' '});
// output: '1 000B'

bytes.format(1024 * 1.7, {decimalPlaces: 0});
// output: '2KB'

bytes.format(1024, {unitSeparator: ' '});
// output: '1 KB'

bytes.parse(string｜number value): number｜null

Parse the string value into an integer in bytes. If no unit is given, or value is a number, it is assumed the value is in bytes.

Supported units and abbreviations are as follows and are case-insensitive:

  • b for bytes
  • kb for kilobytes
  • mb for megabytes
  • gb for gigabytes
  • tb for terabytes
  • pb for petabytes

The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.

Arguments

| Name | Type | Description | |---------------|--------|--------------------| | value | string｜number | String to parse, or number in bytes. |

Returns

| Name | Type | Description | |---------|-------------|-------------------------| | results | number｜null | Return null upon error. Value in bytes otherwise. |

Example

bytes.parse('1KB');
// output: 1024

bytes.parse('1024');
// output: 1024

bytes.parse(1024);
// output: 1024
